j4 Just caught this one.

a friend of mine recently had a 10.5" barrel ar-15 upper made up for his papered legal SBR

on a lark we decided to fire a few rounds through the chrony.

we were shocked to see the 7.62x39 didn't lose much speed at all form the 10.5" barrel. we were sort of expecting the mv to plummet like the 5.56 does from a SBR--

wolf 122gr was pulling 2140fps avg

yugo brass was pulling nearly 2200!

154gr wolf was bumping 2000fps i think the best was like 1997fps

the bad thing is now i am going to have to plunk down that $200 for the stamp--LOL! tis one is loud--a can wouldn't be a bad idea either---LOL

anybody else fire a SBR/pistol 7.62x39 for muzzle velocity??

I have the AK shorty pistol. 7.62x39. Dont know about the speed. But my God is it loud.
You want your ears too feel pain. Stand anywhere near the 7" shorty AR..

Without question.

which is the most noisy 4th the AK pistol or the super-shortie ar-15 with the 7" barrel?

The little AR.. I swear too God. We go across the street in a ditch in the swamp to shoot it safely.
Have you ever seen four grown men, drop too their knees, holding their ears in pain.
Shooting in the open at the ranges is not bad. But I guess, not sure. Must be the echo off the trees in a confined a.o. that makes a cracking noise, like someone stuck ice picks in your ears.
Poor English Mike.

He is a big guy, lifts weights. I should not have let him shoot.

Bluejack. I think I am going too save my pennies and go for a Red Jacket can myself. Their is nobody out my front door for 30 miles or more.
The Sheriffs dont care. My L.O. neighbor even shoots with me. But the damn "River Nazi" Game Warden calls me the AK guy.
More than one shot. He is on the way. The neighbors out the back door all point at my house.
When he gets here. We point at their house.
